A chromatography cartridge stabilized by radial compression is disclosed with integral distributors each composed of two abutting thin plates, one with generally radial slits and the other with radially-displaced apertures. Also disclosed are a replaceable filter cap which fits in the cartridge inlet and a holder for radially compressing the cartridge with pressure sequentially generated by pistons and applied across a flexible sleeve.
